    Does anyone know how far the firing pin precooked on the M&P?

    Also what is the exact trigger pull weight? Heavier than 5.5lbs?

    I have reviewed several reviews and none of them say anything about the percent of precock; two of them tested the trigger pull at 6.5 lbs.

    "Autopistols" mag said this about the striker; "It is striker fired with the striker partly cocked by the forward movement of the slide. Trigger movement retracts the striker about a thousandth of an inch before releasing the striker to fire the pistol". Will keep looking. :roll:

    seems the M&P is prone to the striker breaking just as the Sigma line is. btw I have 2 S&W sigma's brand new VE's both the strikers broke on them with less than 1,000 rounds through. heck my 9ve didnt even have more than 250 rounds.

    broke my (locking block/trigger/trigger spring/slide stop)pin in 40ve after getting the striker replaced.

    put 500 rounds through 40ve before striker broke got it back put 150 through it then pin broke. have had issues with pins walking out under recoil though some loctite helps. the pin that is placed in the middle of the trigger will walk also thats the worse one that could though any pin walking is bad.

    S&W service is good and bad they pay shipping from your place and back send a shipping label atleast for us USA folk. 2 weeks turn around. btw when a striker breaks you have to send the gun in to get the striker replaced.

    wish I bought me Steyr MA1's instead but wanted something with lousy heavy long trigger and good ergonomics.

    precock on sigma is same as glock or close to it. M&P sear is different not sure how much.

    M&P trigger weight is 5lbs though not as crisp as a Steyr nor as short.

    M&P striker was not changed much from Sigma design. I think they make them out of MIM castings or a bad steel. it definately snaps like its overhardened and brittle.

    Burwell does a great job on the trigger. Mine is now about 3 lbs with no overtravel and a VERY short reset.

    think it might be cocked 100% looking at pics of the sear dont see how the striker is cocked any further and released as safe action is.

    The M&P presets to about 70%. The sear is shaped such that as it approaches the release of the striker, it cams the striker back just prior to release.

    looking at pics I have it looks like it has shorter travel than the steyr. looks like the sear just pivots but in regards to the striker and the way the end the sear is beveled cam is not far off.

    is the sear pin hole larger than the pin holding it? looks like the sear just pivots under trigger travel

    Mr. A, The sear just pivots on the pin. The "cam" device is on the back, top edge of the sear. The striker rests against the sear prior to firing. As the sear pivots downward, the cam lobe on the top of the sear moves the striker to the firing position and a lobe on the trigger bar releases the firing pin safety. It is a very simple and effecient system and capable of being smoothed and lightened. The factory trigger is good, the tuned trigger is fantastic. Mine is 3.5 pounds, 1/16th reset and no overtravel.
